Spiritual (not Biblical) names for boys?

Not that I have anything against Biblical names...quite the opposite actually! My boys' list is overrun with them, and I'd like to broaden those horizons. I have so many Christian names that my zen/bohemian/new-age-y side is getting neglected!

I'm searching for names that aren't specifically religious, but do have deeper more spiritual meanings. My guilty pleasure at the moment is Bodhi, and I REALLY need to replace him. I only like the idea of the name, the nature meaning and the associations with enlightenment. I don't even like the sound, and I hate that he's so trendy at the moment, and so stereotypically "woo-woo." I think that if I can collect more names with those richly layered spiritual meanings, I will find it much easier to let go of a name that I only like in theory rather than in practice.

Thanks Berries! I always feel so much better after posting these sorts of internal dilemmas that no one in the "real world" would ever understand...you guys rock my socks!
